A flight by a mystery drone over a Waikato prison has sparked a police complaint amid contraband smuggling fears.
Waikeria prison staff scrambled after the early evening incident on Tuesday, May 10 after they saw the unmanned aircraft flying directly over the site for 10 minutes.
Acting prison director Rosemary Firth said officers searched the grounds but did not find anything dropped by the drone.
Firth said police were notified and drone sightings were not taken lightly by Corrections due to the risk they could smuggle illicit goods.
